When it debuted in 1999, TiVo revolutionized the TV experience by wresting control of screen time from advertisers, allowing viewers to record shows and skip commercials. TiVo's slogan said it all: "TV your way." Behind the scenes, though, TiVo was courting advertisers, selling inroads to a universe most customers saw as commercial-free. The result is a groundbreaking new business strategy, developed with more than 30 of the nation's largest advertisers, that in key ways circumvents the very technology that made TiVo famous.

By March, TiVo viewers will see "billboards," or small logos, popping up over TV commercials as they fast-forward through them, offering contest entries, giveaways or links to other ads. If a viewer "opts in" to the ad, their contact information will be downloaded to that advertiser — exclusively and by permission only — so even more direct marketing can take place.
